Company Annual Return Ireland (Form B1)

The annual return date and the 56-day filing window

Every company has an annual return date. The return must be made up to a date no later than the ARD, and delivered to the CRO not later than 56 days after that effective date. If you make the return up to a date earlier than your ARD, the 56 days run from that earlier date instead. Where the 56-day period expires on a Saturday, Sunday, or public holiday, it extends to the next working day.

Filing is a multi-step process, and only the final step counts. The B1 is not treated as submitted until it has been paid for on CORE, and it cannot be paid for until the financial statements and the signature page have each been uploaded as single PDFs. The B1 can be signed digitally using a ROS certificate, or signed on paper and uploaded. All of that has to be complete inside the 56 days — an uploaded but unpaid submission on day 56 is a late return.

Where financial statements must be attached, a second deadline can bite first. The filing deadline is the earlier of your ARD plus 56 days, or your financial year-end plus nine months and 56 days. The financial statements themselves must be made up to a date no earlier than nine months before the date to which the return is made up, so a stale year-end can force you to change your ARD rather than simply file late.

• 56 days from the effective date of the return, not from the ARD alone
• Deadline extends to the next working day if it falls on a weekend or public holiday
• The B1 is only submitted once it has been paid for on CORE
• Financial statements and signature page must be uploaded before payment

Your first and second annual returns

A new company's first annual return is made up to a date six months from incorporation, and it is the one filing in the company's life that is exempt from annexing financial statements. It is a details-only return: directors, secretary, registered office, share capital, and shareholders. Many founders assume the first deadline is a year away and discover otherwise; six months after incorporation plus 56 days arrives quickly.

The second annual return is where accounts start. It is required to be made up to a date not later than eighteen months from incorporation and must have financial statements attached, again filed within 56 days. Those statements cover the period since incorporation, which for most companies is a longer-than-normal first accounting period.

From then on the cycle is annual, with each return's financial statements covering the period since the end of the period covered by the accounts attached to the previous return. Gaps and overlaps in that chain are a common reason returns get rejected, particularly after an ARD change.

What the financial statements must comply with

Financial statements annexed to an annual return must comply with the Companies Act 2014 and the applicable accounting standards — in practice FRS 102, including the reduced disclosure regime of Section 1A for small companies, or FRS 105 for micro entities. They must be approved and signed by the directors, and where the company does not qualify for audit exemption they must carry a statutory auditor's report.

The reduced regimes cut what appears on the public register, not what you have to prepare. A micro entity filing abridged information at the CRO still needs complete underlying records, and still needs a coherent set of figures for its corporation tax return to Revenue.

That consistency matters more than it appears. Accounts on the public register and the Form CT1 filed with Revenue are both derived from the same year, and contradictions between them are an obvious enquiry trigger. Preparing statutory accounts and the tax computation from one reconciled ledger is the simplest way to avoid explaining a discrepancy you did not intend to create.

• FRS 102, FRS 102 Section 1A, or FRS 105 depending on company size
• Signed by the directors before filing
• Auditor's report required where audit exemption does not apply
• Figures should reconcile to the corporation tax computation

What late filing costs

The financial penalty is mechanical. A late annual return incurs €100 on the day after the deadline, then €3 for every additional day, capped at €1,200 per return. That sits on top of the standard €20 electronic filing fee, and it applies per return — a company that is two years behind is looking at two capped penalties.

The larger cost is audit exemption. A company that files late loses the entitlement to audit exemption for the following two financial years, meaning two sets of audited accounts for a company that would otherwise have needed none. For a small company the audit fees typically dwarf the €1,200 penalty, which is why the deadline deserves more respect than its headline fine suggests.

Persistent non-filing escalates further. The CRO can commence involuntary strike-off, and a struck-off company loses the protection of limited liability, can have its bank accounts frozen, and exposes directors who keep trading to personal liability. Restoration is possible but slow and expensive compared with filing on time.

• €100 immediately, plus €3 per day, capped at €1,200 per return
• Loss of audit exemption for the following two financial years
• Involuntary strike-off risk for persistent non-filers
• Restoration after strike-off is far costlier than compliance

Changing your ARD, and the filings people forget

An ARD can be moved, but the rules are asymmetric. It can be brought forward relatively freely, while extending it is restricted — an extension can generally only be claimed once in every five years, and not on a company's first annual return. Where a nine-month accounts rule is about to be breached, changing the ARD is often the correct fix rather than a workaround.

The annual return is also not the only recurring obligation. Beneficial ownership details must be kept current on the Register of Beneficial Ownership, and that is a separate filing with its own trigger events — a change in ownership or control obliges an update regardless of where you are in the annual return cycle.

Nor does the return replace tax filings. Corporation tax returns to Revenue, VAT periods, and payroll reporting all run on their own timetables from the same year-end. Companies that treat the ARD as the single annual compliance event tend to discover the others late.

How FinnAccountings keeps the cycle on track

FinnAccountings tracks your ARD, the 56-day window, and the nine-month financial statements rule on one compliance calendar, with reminders that escalate as the deadline approaches rather than a single notification you can miss. Because bookkeeping runs continuously on the platform, the numbers behind the accounts are ready weeks before the filing window rather than being reconstructed inside it.

From reconciled records we prepare statutory account drafts and export-ready packs, and align them with the corporation tax computation so the public register and Revenue see a consistent set of figures. Our Chartered Accountant team provides insight on AI-generated drafts before they reach you.

You or your qualified adviser complete the CORE submission and sign the return. FinnAccountings is preparation software rather than a filing agent, and AI has no legal accountability for what is delivered to the CRO in the company's name.

• ARD, 56-day window, and nine-month accounts rule on one calendar
• Statutory account drafts generated from reconciled bookkeeping
• Accounts aligned with the corporation tax computation
• Chartered Accountant insight before you or your adviser file on CORE
